Dynamic OPC Path referencing an internal Query Tag within UDT

Ignition

Hi everyone,

I’m looking for a way to streamline my UDT definition and I’ve hit a bit of a roadblock regarding tag referencing.

Inside my UDT, I have a folder named Position_ID which contains a Query Tag named Extruder. This query automatically retrieves the correct identifier from a database based on the {RootInstanceName} of the UDT.

I have an OPC Tag within the same UDT that requires a dynamic OPC Path. This path needs to be built using the value returned by the Extruder Query Tag.

How can I reference the value of the internal Extruder tag directly within the OPC Path configuration?

I want to avoid adding a manual UDT Parameter just to duplicate a value that is already being fetched by the Query Tag. I've tried a few syntax variations, but the OPC Path doesn't seem to resolve when pointing to a tag value instead of a parameter.

Thanks!
